Markdown.ColorCode

About The Project

An extension for Markdig that adds syntax highlighting to code through the power of ColorCode.

Demonstration

Before

using Foo.Bar.Baz;

namespace Foo.Api;

public interface FooService {
    /// <summary>
    ///     Gets a new Foo!
    /// </summary>
    /// <returns>A new Foo</returns>
    public void GetFoo() {
        return new Foo();
    }
}

After

using Foo.Bar.Baz;

namespace Foo.Api;

public interface FooService {
    /// <summary>
    ///     Gets a new Foo!
    /// </summary>
    /// <returns>A new Foo</returns>
    public void GetFoo() {
        return new Foo();
    }
}

Installation

Package Manager

Install-Package Markdown.ColorCode -Version 2.3.0

.NET CLI

dotnet add package Markdown.ColorCode --version 2.3.0

Usage

To use this extension with Markdig, simply install the Markdown.ColorCode package use the ColorCode extension:

var pipeline = new MarkdownPipelineBuilder()
    .UseAdvancedExtensions()
    .UseColorCode()
    .Build();

var colorizedHtml = Markdig.Markdown.ToHtml(someMarkdown, pipeline);

Several optional configuration options are also at your disposal:

var pipeline = new MarkdownPipelineBuilder()
    .UseAdvancedExtensions()
    .UseColorCode(
        HtmlFormatterType.Style, // use style-based colorization (default)
        myCustomStyleDictionary, // use a custom colorization style dictionary
        myAdditionalLanguages, // augment the built-in language support
        myCustomLanguageId // set a default language ID to fall back to
    )
    .Build();

var colorizedHtml = Markdig.Markdown.ToHtml(someMarkdown, pipeline);

Improved C# Syntax Highlighting

For an improved experience with C# code blocks, consider using the Markdown.ColorCode.CSharpToColoredHtml package. This package provides a more robust syntax highlighting experience for C# code blocks by leveraging CSharpToColouredHtml.Core.

var pipeline = new MarkdownPipelineBuilder()
    .UseAdvancedExtensions()
    .UseColorCodeWithCSharpToColoredHtml(
        HtmlFormatterType.Style, // use style-based colorization (default)
        myCustomStyleDictionary, // use a custom colorization style dictionary
        myHtmlEmitterSettings, // configures CSharpToColouredHtml's HTML emitter
        myAdditionalLanguages, // augment the built-in language support
        myCustomLanguageId // set a default language ID to fall back to
    )
    .Build();

var colorizedHtml = Markdig.Markdown.ToHtml(someMarkdown, pipeline);

Note

The CsharpToColouredHTML package introduces dependencies which will not work well with Blazor WebAssembly projects. Either generate the HTML on the server side and send it to the client or use the base Markdown.ColorCode package if you are working with Blazor WebAssembly. See dotnet/aspnetcore#27373 and dotnet/aspnetcore#26724 for more details on the problem.
